at once a humbler appreciation of what is within our power, and--I think also--a more really hopeful anticipation of genuine progress in the future. All scientific inquiry is an interrogation of nature. We have, in Bacon's grand sententious phrase, to command nature by obeying. We learn what are the laws of social growth by living them. The great difficulty of the interrogation is to know what questions we are to put. Under the guidance of metaphysicians, we have too often asked questions to which no answer is conceivable, like children, who in first trying to think, ask, why are we living in the nineteenth century, why is England an island, or why does pain hurt, or why do two and two make four? The only answer is by giving the same facts in a different set of words, and that is a kind of answer to which metaphysical dexterity sometimes gives an air of plausibility. More frequently our ingenuity takes the form of sanctioning preconceived prejudices, by wrapping up our conclusion in our premisses, and then bringing it out triumphantly with the air of a rigorous deduction. The progress of social science implies, in the first place, the abandonment of the weary system of hunting for fruitful truths in the region of chimeras, and trying to make empty logical concepts do the work of observation of facts. It involves, again, a clear perception of the kind of questions which can be profitably asked, and the limits within which an answer, not of the illusory kind, can really be expected. And then we may come to see that, without knowing it, we have really been trying a vast and continuous experiment, since the race first began to be human. We have, blindly and unconsciously, constructed a huge organism which does, somehow or other, provide a great many millions of people with a tolerable amount of food and comfort. We have accomplished this, I say, unconsciously; for each man, limited to his own little sphere, and limited to his own interests, and guided by his own prejudices and passions, has been as ignorant of more general tendencies as the coral insect of the reef which it has helped to build. To become distinctly conscious of what it is that we have all been doing all this time, is one step in advance. We have obeyed in ignorance; and as obedience becomes conscious, we may hope, within certain narrow limits, to command, or, at least, to direct. An enlarged perception of what have been the previous results may enable us to see what results are possible, and among them to select what may be worthy ends. It is not to be supposed that we shall ever get beyond the need of constant and careful experiment. But, in proportion as we can cultivate the right frame of mind, as each member of society requires wider sympathies and a larger horizon, it is permissible to hope that the experiments may become more intelligent; that we shall not, as has so often been done, increase poverty by the very remedies which are
